Under the guidance of the Nuclear Science Committee the Working Party will deal with reactor physics, radiation transport and dosimetry and fuel performance for present and future nuclear power systems. As such, it will study the modelling of reactor systems and the uncertainties associated with such analyses.


Reactor physics aspects considered will include:

Radiation transport and dosimetry will cover aspects relevant to reactor vessels and internals, and irradiation facilities.

Reactor types considered include, but are not limited to the following:

The Working Party will liaise closely with other relevant NEA working parties, especially those operating under the guidance of the NDC and CSNI, to ensure the respective work programmes are complementary and to provide advice and support where required and undertake common work where appropriate. Particularly close working relationships will be maintained with the NSC Working Party on Scientific Issues of Fuel Cycle (WPFC) and will be developed with the Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems (WPMM) and other relevant NSC working parties.
